anyone catch the "top secret rocket launch" out west tonight? We were just west of Denver heading west and the entire sky above the horizon from 10-2oclock lit up as if there was a giant headlight in space along with a bright glow across the heavens. Lasted a good 5mins. Atc had no clue what it was. Finally we were told that it was a rocket launch over OAL (Coaldale... Area 51??) Dispatch suggested secret military operations going on. Anyone know?
